Due selvaggi a corte (1959) as Rebel

La spada normanna (1971) as Fighter for Ivanhoe

Hard to be absolutely certain as he's only seen fleetingly in movement from a strange angle, but I'm pretty sure this is him in the fight following the hanging. Franco and Giancarlo (and possibly Clemente) also appear

L'arciere di fuoco (1971) as Fighter for Robin Hood

As with this film's companion piece, La spada normanna, Bruno is only seen fleetingly among a bunch of other stuntmen at the end of the first big fight

Kean (1955) (Tv movie) credited as Poum in the cast list of radiocorriere Tv magazine and also
credited on a very bad Youtube copy of this filmed play (the ID was not possible to identify) of the movie
with the same title and same actor, Vittorio Gassman. Confusingly enough, the version on youtube (https://www.youtube.com/watch?v=1cCK2ABKEhw) seems to be a THIRD version, cause (as an example) Luigi Vannucchi is playing the part of ´Il principe de Galles`here...
So this is the earliest role found so far, the next one is four years later !

Corsaires et flibustiers (1966) (TV series) as Pirate

This 13-part French swashbuckler TV series was shot in Italy, but does not appear to have been an Italian co-production and was not broadcast in Italy until in 1972 under the title Il corsaro. Of the 13 episodes, Bruno appears in four:

Episode 7: "L'Olonais" (the Italian title was "L'Olonese")
Episode 8: "Le rendez-vous" (the Italian title was "L'appuntamento")
Episode 9: "L'or de Maracaï" (the Italian title was "L'oro di Maracai")
Episode 12: "Le complot" (the Italian title was "Il complotto")

La rivolta dei pretoriani (1964) in dual roles as a Rebel and a Guard. Credited as Fencing master. Credit shot added

Tecnica di una spia (1966) credited as Stunts master, as Otis henchman, seen in the pre-credit ship attack

I due figli di Ringo (1966) as Mexican bandit

La tarantola dal ventre nero (1971) credited as "Director stuntman".

Bruno does not appear, nor do any stuntmen that I could see, so I'm uncertain exactly what he is being credited for.

I due gladiatori (1964) credited as Master of Arms, as a Rebel and, maybe, in a second role as a Servant stealing food.

There was universal uncertainty over the second role, due to him looking rather strange under a blonde wig, but I'm pretty convinced that it is Bruno.
